Description

Technical Field

[0001] This utility model belongs to the technical field of trolley auxiliary devices, and relates to a trolley step walking auxiliary device. Background Technology

[0002] During the construction of dam panel concrete, due to the phased pouring of the panels, after the reinforcement and panels of some sections are poured, materials need to be transported on the panels of the sections that have already been poured. Due to the thickness of the panels, there are steps between adjacent panels, which makes it easy for the trolley to get stuck at the steps when transporting materials, making it difficult to go up and down, and posing a risk of trolley instability and material falling. At present, steel trestle bridges are usually set up on the dam panels to assist the movement of the trolleys. However, steel trestle bridges are bulky and difficult to disassemble. The safety risks for workers transporting materials on the panels are still very high, which can easily lead to safety accidents. Therefore, there is an urgent need for an auxiliary device that facilitates the movement of trolleys on the dam panels. Utility Model Content

[0003] The purpose of this invention is to provide a trolley step walking auxiliary device, which solves the problems of trolley instability and material falling risk when the trolley travels on the dam panel in the prior art.

[0004] The technical solution adopted by this utility model is a trolley step walking auxiliary device, which includes two triangular supports. One angle of the triangular support is a right angle or an obtuse angle. The two triangular supports are arranged opposite each other. Several locking blocks are fixed at equal intervals on the long side of the triangular support, and two of the locking blocks are located at the adjacent ends. Several crossbeams are connected to the long side of the two triangular supports through the locking blocks in a one-to-one correspondence.

[0005] The features of this utility model trolley step walking auxiliary device are also as follows:

[0006] The crossbeam is made of I-beams, and the flange ends of the I-beams abut against the locking block.

[0007] The triangular support includes a base beam. Several telescopic beams and a rotating beam are fixed vertically side by side on one side of the base beam, with the rotating beam located at the end of the base beam. The other ends of the telescopic beams and the other ends of the rotating beam are jointly fixed to an inclined beam. The two ends of the rotating beam are fixed to the rotating beam and the base beam, respectively. Several locking blocks are fixed on the inclined beam, with one end of the rotating beam facing one of the locking blocks.

[0008] Diagonal bracing is installed between two adjacent telescopic beams and between the telescopic beam and the rotating beam. One end of the diagonal bracing is fixed to the inclined beam, and the other end is fixed to the bottom beam and the corresponding telescopic beam.

[0009] One end of the telescopic beam is fixed to the inclined beam by bolts.

[0010] A fixing plate is hinged to the clamping block opposite the inclined beam and the rotating beam.

[0011] The angle between the bottom beam and the inclined beam shall not exceed 20°.

[0012] Several first adsorption rods are fixed side by side on the side of the rotating beam away from the telescopic beam.

[0013] Several second adsorption rods are fixed side by side on the side of the bottom beam away from the telescopic beam.

[0014] The beneficial effects of this utility model are:

[0015] Compared with existing technologies, this utility model of a trolley step walking auxiliary device has a simple structure, flexible operation, and is safe and practical. It can accelerate the construction progress of dam panel concrete and reduce operational safety risks. The connection between the first and second adsorption rods and the panel ensures the stability of the trolley during travel. The flange end of the I-beam abuts against the locking block, which not only secures the I-beam but also ensures that the trolley will not run over the flange end during travel, thus protecting both the trolley and the I-beam. The locking block prevents the crossbeam from shifting or vibrating during trolley travel. The trolley step walking auxiliary device is easy for operators to disassemble and transport. Only the first and second adsorption rods can be disassembled for hoisting, or all components can be disassembled for manual transport, reducing the safety risks for operators during transport. It can also be used on steps and steep slopes to assist vehicle passage. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Trolley step walking auxiliary device, refer to Figure 1It includes two triangular supports 1, one angle of which is a right angle or an obtuse angle, to ensure that the trolley step walking auxiliary device can be erected on the panel. The two triangular supports 1 are set opposite each other, and several locking blocks 2 are fixed side by side at equal intervals on the long side of the triangular supports 1, with two of the locking blocks 2 located at the adjacent ends. Several crossbeams 3 are locked together on the long side of the two triangular supports 1 through the locking blocks 2. The locking blocks 2 can prevent the crossbeams 3 from shifting and vibrating during the movement of the trolley.

[0021] The crossbeam 3 is an I-beam. The flange end of the I-beam abuts against the locking block 2, which can not only lock the I-beam, but also ensure that the trolley will not run over the flange end during travel, thus protecting both the trolley and the I-beam.

[0022] The triangular support 1 includes a base beam 11. Several telescopic beams 13 are vertically and parallelly fixed to one end of one end of a rotating beam 12, with the rotating beam 12 located at the end of the base beam 11. The telescopic beams 13 can change length with the rotation of the rotating beam 12 to adapt to panels with different inclination angles. The length of the telescopic beams 13 can also be adjusted to allow the base beam 11 to be placed on any panel. An inclined beam 15 is fixed to the other end of the telescopic beams 13 and the other end of the rotating beam 12. Both ends of the rotating beam 12 are fixed to the rotating beam 12 and the base beam 11, respectively. Several locking blocks 2 are fixed to the inclined beam 15, with one end of the rotating beam 12 facing one of the locking blocks 2. Diagonal braces 14 are provided between adjacent telescopic beams 13 and between the telescopic beam 13 and the rotating beam 12. One end of the diagonal brace 14 is fixed to the inclined beam 15, and the other end is fixed to the base beam. 11 and the corresponding telescopic beam 13 are simultaneously fixed. The diagonal brace 14 can ensure the stability of the diagonal beam 15 and the telescopic beam 13. One end of the telescopic beam 13 is fixed to the diagonal beam 15 by bolts 5, which can prevent the diagonal beam 15 from shifting. The clamping block 2 opposite to the diagonal beam 15 and the rotating beam 12 is hinged with a fixing plate 4. The fixing plate 4 can be rotated 90° and then clamped to the top of the panel. The rotation of the rotating beam 12 can ensure that the included angle between the bottom beam 11 and the diagonal beam 15 is not greater than 20°, reducing the risk of tipping over during the trolley's movement. Several first suction rods 6 are fixed side by side on the side of the rotating beam 12 away from the telescopic beam 13, and several second suction rods 7 are fixed side by side on the side of the bottom beam 11 away from the telescopic beam 13. The first and second suction rods can be connected to the panel to ensure the stability of the trolley during movement.

[0023] The trolley step walking auxiliary device is easy to disassemble after use. Only the first suction rod 6 and the second suction rod 7 can be disassembled to lift the trolley step walking auxiliary device, or all parts can be disassembled and carried manually.

[0024] The working principle of this utility model is as follows:

One end of the bottom beam 11 is fixed to the ground, and the other end of the bottom beam 11 is fixed to the step formed by one of the panels. The top of the rotating beam 12 abuts against the top of the uppermost panel. The distance between the two trolley step walking auxiliary devices is less than the width of the trolley. The crossbeam 3 is used as the traveling surface of the trolley.

[0026] Adjust the rotation angle of the rotating beam 12 so that the first adsorption rod 6 and the second adsorption rod 7 are adsorbed onto the corresponding panels. At the same time, rotate the fixing plate 4 to lock it onto the top of the panel. One trolley travels on the crossbeams 3 of the two trolley step walking auxiliary devices to transport materials. After the materials are transported, only the first adsorption rod 6 and the second adsorption rod 7 can be disassembled to hoist the trolley step walking auxiliary device, or all parts can be disassembled and manually transported.
